` The invention relates to new and useful i improvements in :latherforming devices for shaving purposes, of the same general-type disclosed in myv ZU. S. fPatents V1,554z,146;

` u 1,554,147 and 1,554,148a11 of sepc. 15, 1925,

and in my pending U. S. applicationv Serial No. 174,320. 'i A great many users of lather forming devices such as those above referred to, often 1,0 rest the device upon a radiator or other warm support, Vtoheat the contained liquid for the purpose of obtaining'a warm'lather, andV O the inlets throughV which air/under pressure or other gas is forced into the liquid and soap containing Chamber for the purpose ofl generating bubbles, which'bubbles are laterV condensed and converted 'into thick creamy w, lather.

It is one object of the present invention to provide new and improved means whereby any accumulated soap' in the lower portion of the liquid container, may beV vreadily 430 loosened to again exposethe gas inlets .so that the device may be readily used.

Lather forming devices of the general type to which I have above referred, embodya cap atl the upper vend of the device, capable of being manually turned, and it is a further aim of the invention to provide a construction in which turning of this cap will actuate the soap loosening means. In this connection, a still further aim is to provide a construction in which the bubble condensing or converting unit acts as an intermediate driving member between the cap and the soap'loosening means.

Yet another aim is to'provide a construction which, whilebeing rather simple and inexpensive, will be eificient, reliable and in every way desirable. o

V With the' foregoing in view, the invention resides in the novelsubject matter' here'in'- after described and claimed, the description being made with reference to the accompanying drawing.

F igure 1 is a Vertical sectional view partly inelevation, showing a lat-her forming device improved in accordance with the present invention.

F ig. 2 is a horizontal secti-onal viewon line 2 -2 of Fig. ;1. Z

Fig. 3 is a perspective view'showing the soap loosening device, and the bubbleconverting unitin juXta-position.

In the drawing above briefly described, the numeral 4 denotes a container adapted to receive a vquantity of water or other des'ired liquid. At 'the'c'entral portion of this container, is a post structure 5 at Whose lower portion, a .soap cake support 6 is provided. Gas Outlet ducts 7 arelocated under the support 6 and are open at the peripheral edge i of the latter, which edge is spaced from the peripheral ,wall lof the container 11. The container bo'ttom and the post structure 5 are formed with suitable gas conducting passages 8-9-10-11, for conducting gas (preferably air\ to the ducts 7 from a suitable source such as a hand bulb 12. The injection of this gas into the liquid, into which the soap cake 13 extends, serves to .form soap bubbles. Un der the influence of'thepressure within the bubble forming portion of. the container 11-, the bubbles are extruded througha cylindrical bubble condensing unit 14; which `con'- verts them into a thick creamy shaving' lather. This condensing unit 14 is rotatabl'y received in the upper portion of the containerV 4 and fitting over the upper portion of said unit, is a cap l'having al lather discharge spout 16, said cap being connected with the body of the container by a suitable lock ring 17 which whenV loosened permits turning .of

the cap 15 to'dispose the spout 16 in any desired direction. w o

lThe features of construction so far disclosed constitute no parts of the present invention eXcept in their relation with the new features of construction now to be described.

18 denotes soap loosening means disposed in the container 4, said means preferablyvv proj ecting downwardly from 'said ring, the

lower ends of said arms being provided with ears or other desired formations such as 21, received between the' peripheral wall of the container 4 and the peripheral edge of the support 6.v Preferably, the parts 19-20-21 are stamped from a I single Vpiece offsheetmeta1, and the arms may be sc stamped as to provide them with longitudinal ridges 22 for stifl'ening purposes.V j If ldesired, the encls of p the split ring 19 may have an interlocking-.engagement 'to preventsuch ends from shiftlng o up and down when the soap loosening or cutting means is rotated. As shown in Fig. V3, 15/

one end of the ring mayhave a notch 19a toreceive a tongue 19b formed byreducingthe other end, or any other suitable means may beV V ;employed to keep the ends ofthe ring 1n An operative connection is 'provided between the soap. loosening means or device 18 and the 'bubble condensing or convertingunit 14, seo that upon turning of the latter, vthe means 18 will be operated to loosen any' accumulated soap between the'peripheral edge of thefsupport 6 and the peripheralwallof the'container`4. I'falso provide an operative i o connection between the cap 15 andt'he unit 14,

so that by turning said cap manually' upon. loosening of the ring 17 said-,unit 14 maybe similarly turned. i Hence, it will be seen that i unit 14 forms an intermediate driving'conioi i i p The operative connection between the soap nection between the cap V15 and the soap loosening means or device 18, iso' `that by merely turning saidfcap, the lowerfiends vof the arms 20 will plow through any'accumu-v lated soap at the peripheral edgev of the support 6, thus so loosening it as to permit free discharge of gas into the containerfrom the' ducts 7 loosening means-or device 18 andrthe bubble condensing or converting unit' 14, preferably consists of co-ope'rabl'e circum'ferentially spaced lugs V23-24'on the upperedge of the ringr 19 and the lower 'corner of the unit 14.

,`Similarly, the operative connection between the unit 14 and the cap 15, preferably consists of co-operable circumferentially spaced 50` o lugs 25-26. i V- i o While ;the presentillustrated em'bodiment of the invention is've'specially adapted for forming lather for shaving purposes, it will be understood that my invention mayV be embodied,v in largerl devices or machines for making Alather for purposes other than shaving,and when this is done, the soap loosening or Cutting feature would be more essential than in theysmaller devices ofv my patents above mentioned. f

Excellent results are obtainable from the construction shown and described and hence jitemay be consi'dered'as preferred. However,rwithinthe scope of the invention' as i ceous liquid, and a removable cover swiveled i i uponfthe upper -end of the container wall,
